Weekly Photo Challenge: Intricate, Or: Wine Glass Reflections

Wine Glass Reflections

This week’s challenge calls for something intricate, and I immediately thought of this wall at the Exploratorium.This is part of the “Simply Smashing” exhibit by Rebecca Cummins: A 20-foot wall of about 900 glasses, all filled with water to create optical effects with the reflections. Large version available here. Another angle can be seen here.

Weekly Photo Challenge: Wave In A Bottle

Wave In A Bottle

Do not adjust your set; that really is a wave suspended in a kind of glass! One of the exhibits at the Exploratorium, the Confused Sea shows how the wind affects the motion of the ocean. You can change the speed and direction of air, thus creating some choppy water!

Weekly Photo Challenge: Spinning Ring In Light And Shadow

This week’s photo challenge calls for something blurry. I recalled something I saw at the Exploratorium on Pi Day: People could take large metal rings and spin them on a curved table. As a result of the altered surface (thus influencing the balance and center of mass), the spinning ring maintained its energy for much longer than it would have on a flat surface. Having a bright light made this physics exhibit a little more stylish. Since this is for a photo challenge, here’s a single shot of the ring in motion:
